Diaphragmatic Ultrasound and Thoracic Fluid Content for Prediction of Non-Invasive Ventilation Failure in Neonates

Diaphragmatic thickening fraction (DTF) and diaphragmatic excursion (DE) were measured by ultrasound within the first three hours of life and repeated either 24 hours later in successful cases or immediately before intubation in cases who had NIV failure.

TFC was assessed using electrical cardiometry (EC). Measurements were obtained within the first three hours of life and repeated either 24 hours later in successful cases or immediately before intubation in cases who had NIV failure.
